Symfony2 MongoDB Multiple Connection Error

Question

I have a problem setting up MongoDB in Symfony2.

Specifications:

"Symfony": "2.6.*" "doctrine/mongodb-odm": "1.0.*@dev", "doctrine/mongodb-odm-bundle": "3.0.*@dev" 

I have 2 databases used in two different packages, nxtlog and nxtsurvey, in MongoDB. The original problem was that the db name that I added in the parameters was not taken into account, which led to the use of the default database, which, of course, does not exist. I also do not want to add default_connection and default_manager, and even default_database, since both connections are used in non-core packages.

==== Attempt # 1 ====

Here is the original configuration I had:

 doctrine_mongodb: connections: nxtlog: server: "%nxtlog_database_server%" options: username: "%nxtlog_database_username%" password: "%nxtlog_database_password%" db: "%nxtlog_database_name%" nxtsurvey: server: "%nxtsurvey_database_server%" options: username: "%nxtsurvey_database_username%" password: "%nxtsurvey_database_password%" db: "%nxtsurvey_database_name%" document_managers: nxtlog: mappings: NxtLogBundle: ~ nxtsurvey: mappings: NxtVibeSurveyBundle: ~ 

To make it work, I added the db name to each document annotation:

 /** * @MongoDB\Document(db="nxtlog") */ class ErrorLogs 

This is a temporary solution, but since my plan is to reuse packages in my other projects, I do not want to go through all the documents and set the db name.

==== Attempt # 2 ====

My second attempt was to strictly follow the documentation, and so I tried the following:

 doctrine_mongodb: connections: nxtlog_conn: server: "%nxtlog_database_server%" options: username: "%nxtlog_database_username%" password: "%nxtlog_database_password%" connect: true db: "%nxtlog_database_name%" nxtsurvey_conn: server: "%nxtsurvey_database_server%" options: username: "%nxtsurvey_database_username%" password: "%nxtsurvey_database_password%" connect: true db: "%nxtsurvey_database_name%" document_managers: nxtlog_dm: connection: nxtlog_conn mappings: NxtLogBundle: ~ nxtsurvey_dm: connection: nxtsurvey_conn mappings: NxtVibeSurveyBundle: ~ 

And get the following error:

 ServiceNotFoundException in CheckExceptionOnInvalidReferenceBehaviorPass.php line 58: The service "doctrine_mongodb.odm.nxtlog_conn_connection" has a dependency on a non-existent service "doctrine_mongodb.odm.nxtlog_conn_configuration". 

So, I realized that I cannot have different names for connections and data managers. Which I did not believe, so I was looking for it, and someone had a similar problem, and the answer was to add the following to doctrine_mongodb:

 default_commit_options: ~ 

But this solution did not work for me, and after more searches, I found out that jmikola, the guy who wrote the kit (or parts of it) made a mistake, he said that he fixed it, and that default_commit_options should not be a required configuration . (link https://github.com/doctrine/DoctrineMongoDBBundle/issues/222 )

At this point, I will need help because it takes too much time.

thanks

Answer 1

Quite a long time ago I tried to establish several Doctrine connections, although at that time I used the Zend Framework (and the corresponding Doctrine modules). If I remember correctly, you need to configure all Doctrine services with the new namespace added (in your case nxtlog_conn ).

I checked the source of the ZF2 DoctrineMongoODMModule and I still remember it: if you want to connect, you need a Doctrine configuration service with a prefix with the same namespace.

Judging by your error message, this also applies to the Symfony package, although I could not find a responsible place in the package source code.

The "doctrine_mongodb.odm.nxtlog_conn_connection" service has a dependency on the "doctrine_mongodb.odm.nxtlog_conn_configuration" service.

This basically tells you: I want a connection, but wait a second, I can’t find the appropriate configuration!

Try to find out how the configuration is configured to connect orm_default , and configure your configuration as wise. If you encounter another error of the same format, find the next required service name, then flush and retry.

Hum is not sure, but hope this helps. Here is a link from the google group https://groups.google.com/d/msg/doctrine-user/6YCVAZ4h4nA/YrZNfSopmNUJ
